Do see the posting guide, and do not re-post
(https://stat.ethz.ch/pipermail/r-help/2014-November/423727.html).
I suspect I am not alone in not knowing what you are talking about (even
though I am the rpart maintainer). Please do try to explain clearly
what you mean with the reproducible example asked for in the posting
guide, and show us the output you get and want to understand.
And a hint: rpart cross-validation is random, so set a seed and include
that in your 'reproducible example'.

Dear Users,
Is it possible to get cycling and different xerror scores in cp of rpart while
getting the same tree on every run (or am I missing something or understood
wrong)? I build it with an old version of R in a Windows VM installed on a
Intel based macbook and reuse the same codes with a newer version of R and
required packages on an AMD pc installed with standalone Windows. Both Windows
are 64bit, which result should I trust, the old one or new one, macbook or pc?
Thanks in advanced,
Levent TERLEMEZ.
